mod_mem_cache
Overview
This module requires mod_cache to be enabled.
It acts as a supporting module for mod_cache and implements memory-based storage engine.
mod_mem_cache is most useful when used to cache locally generated content or backend server content.
mod_mem_cache uses System.Web.Caching class for caching.
This cache class has separate storages for each http-application (application pool).
So, for each current request System.Web.Caching
uses the cache storage of the application which handles the request.
Similarly, cache cleaning using cache-clear environment variable empties
the cache for http-application of the current request (request that triggered cache cleaning).
Quick start
To enable memory-based storage engine for mod_cache use this minimum httpd.conf configuration:
CacheEnable mem /myapp/
or myapp direcotory .htaccess configuration:
CacheEnable mem
# or via env
SetEnv cache-enable mem
This configuration clears cache on specified request.
Request must contain 'cache_clear_request' in query string:
SetEnvIf Query_String cache_clear_request cache-clear=1
